[mythtv-users] Moving of old recordings to another Storage Group

Hi All,

Imaging the following disk/storage group layout:

Default: /var/lib/mythtv/recordings/
recordings_old: /var/lib/mythtv/recordings_old/

/var/lib/mythtv is a remote mount point (NFS)
/var/lib/mythtv/livetv is a local mount point*
/var/lib/mythtv/recordings is a local mount point*

* Mounted locally due to lag on the network causing pauses in LiveTV when 
a new program starts, that also happen to be recorded (this, from my 
investigation, generates a file in livetv/ and recordings/)

Due to the above lag issues, I would like to have the livetv stuff as 
local, including recordings. The "problem" is that /var/lib/mythtv is a 
2TB mount which now only houses my ripped DVDs, not something that 
grows much. It seems to be a waste of space, so I came up with the idea of 
"expiring" old recordings to the NFS mount. The chances that they will be 
accessed is slim, but one never knows.

I wrote a script to find the recordings older than 7 days, then move them 
to /var/lib/mythtv/recordings_old/ and update the DB. From what I 
understand, the DB update is not *needed*, but I prefer to keep it clean.

Comments/Suggestions welcome !

Pending above comments/suggestions this will make it's way to the feature 
request wiki :)

Change the variables at the top of the script to suite your local needs.

The script can be downloaded at:


* Read the SG_SDIR and SG_TDIR from the DB
* Fix bugs/implement suggestions ?
